Revelation 22:5: And there shall be no night there; and they need no candle, neither light of the sun; for the Lord God giveth them light: and they shall reign for ever and ever.

Revelation 21:23 previously indicated that there shall be no night in the celestial kingdom because the Father provides light continually through his Son, Jesus Christ.¹ The angel further explains in Revelation 22:5² the contrast between the light of celestial glory and the relative darkness of this fallen world, both physically and spiritually.³

The angel mentions a candle and light of the sun as two types of light that will not exist in the celestial kingdom.⁴ The candle represents artificial or manmade light of the earth,⁵ which is so far inferior to the divine light and glory of the Father that the two cannot coexist in the same space.⁶ This is akin to light and darkness that cannot coexist.⁷ Additionally, the celestial kingdom will not require any natural light of the sun because the entire resurrected earth will emit celestial light and glory.⁸ The very presence of the Lord God giveth ... light⁹ to all God's exalted children.¹⁰ The angelic voice implicitly identifies God's exalted children as the recipients of God's light because they that receive this light are those that shall reign for ever and ever.¹¹

Before John's epilogue to the Book of Revelation begins in Revelation 22:6,¹² his vision of the celestial kingdom concludes in Revelation 21:5 with a final emphatic statement that God's most faithful children will possess God's light;¹³ they will become as he is;¹⁴ they will do as he does.¹⁵ They shall reign forever and ever¹⁶ over unexalted angels in the celestial kingdom,¹⁷ and over those in all lesser kingdoms of glory.¹⁸ Exalted saints shall be kings and queens in the house of Israel forever.¹⁹ They will follow in God's footsteps and continue his creative activities²⁰ from one generation of spirit offspring to the next.²¹ This is the final and strongest encouragement in the Book of Revelation for all saints²² to overcome even the most severe tribulations and trials in this life.²³
